A comprehensive Neovim smooth motion plugin, providing fluid animations for all motion commands.
Combines smooth cursor movement, word navigation, text objects, and viewport scrolling into one seamless experience.

---

✨ Features

• Smooth Animations

  • 60fps fluid animations for all Vim motion commands
  • Unified smooth cursor movement and viewport scrolling
  • Works in Normal and Visual modes with count prefixes

• Extensive Movement Coverage

  • Basic: h, j, k, l, 0, $
  • Word Navigation: w, b, e, W, B, E
  • Find/Till: f, F, t, T (supports counts)
  • Text Objects: {, }, (, ), %
  • Line Jumps: gg, G, |
  • Search Navigation: n, N
  • Screen Lines: gj, gk
  • Viewport Scrolling: <C-d>, <C-u>, <C-f>, <C-b>, zz, zt, zb

• Performance & Optimization

  • Object pooling and frame reuse to reduce garbage collection
  • API call caching (50ms window) for efficient redraws
  • Optimized for smooth 60fps animations
  • Performance Mode for faster but less smooth rendering:
    • Reduces animation duration and easing complexity
    • Optional syntax highlighting toggle for large files

• Flexible Configuration

  • Separate settings for cursor and scroll animations:
    • Duration (ms)
    • Easing function (linear, ease-out, ease-out-quad)
    • Enable/disable individually
  • Keymap control:
    • Enable/disable default mappings
    • Define custom mappings for any motion
  • Easily toggle performance mode at runtime

• Comprehensive Command & API Support

  • Commands:
    • :LuxMotionEnable / :LuxMotionDisable / :LuxMotionToggle
    • :LuxMotionPerformanceEnable / Disable / Toggle
  • Lua API:
    • Enable/disable cursor and scroll animations
    • Toggle performance mode
    • Trigger manual smooth motions for custom keymaps

• Customization & Extensibility

  • Different speeds and easing curves for cursor vs scrolling
  • Integrate with custom motions or other keymaps
  • Visual mode motions supported out-of-the-box

• Compatibility

  • Neovim ≥ 0.7
  • Designed to coexist with other scroll/motion plugins (disable keymaps if needed)

📦 Installation

Using lazy.nvim

{
  "LuxVim/nvim-luxmotion",
  config = function()
    require("luxmotion").setup({
      cursor = {
        duration = 250,
        easing = "ease-out",
        enabled = true,
      },
      scroll = {
        duration = 400,
        easing = "ease-out",
        enabled = true,
      },
      performance = { enabled = false },
      keymaps = {
        cursor = true,
        scroll = true,
      },
    })
  end,
}

Using packer.nvim

use {
  "LuxVim/nvim-luxmotion",
  config = function()
    require("luxmotion").setup()
  end
}

Using vim-plug

Plug 'LuxVim/nvim-luxmotion'

Then in your init.lua or init.vim:

lua << EOF
require("luxmotion").setup()
EOF

🛠️ Configuration

require("luxmotion").setup({
  cursor = {
    duration = 250,       -- Cursor animation duration (ms)
    easing = "ease-out",  -- Cursor easing function
    enabled = true,
  },
  scroll = {
    duration = 400,       -- Scroll animation duration (ms)
    easing = "ease-out",  -- Scroll easing function
    enabled = true,
  },
  performance = {
    enabled = false,      -- Enable performance mode
  },
  keymaps = {
    cursor = true,        -- Enable cursor motion keymaps
    scroll = true,        -- Enable scroll motion keymaps
  },
})

🔧 Lua API

local luxmotion = require("luxmotion")

-- Global control
luxmotion.enable()
luxmotion.disable()
luxmotion.toggle()

-- Individual controls
luxmotion.enable_cursor()
luxmotion.disable_cursor()
luxmotion.enable_scroll()
luxmotion.disable_scroll()

-- Performance mode
local performance = require("luxmotion.performance")
performance.enable()
performance.disable()
performance.toggle()
performance.is_active()

-- Manual motion (if custom keymaps are used)
local cursor_keymaps = require("luxmotion.cursor.keymaps")
cursor_keymaps.smooth_move("j", 5)
cursor_keymaps.smooth_word_move("w", 3)
cursor_keymaps.smooth_find_move("f", "x", 2)
cursor_keymaps.smooth_text_object_move("}", 1)

🎨 Customization Examples

Disable Default Keymaps

require("luxmotion").setup({
  keymaps = {
    cursor = false,
    scroll = false,
  },
})

-- Define your own
local cursor_keymaps = require("luxmotion.cursor.keymaps")
vim.keymap.set("n", "j", function()
  cursor_keymaps.smooth_move("j", vim.v.count1)
end)

Different Speeds for Cursor vs Scroll

require("luxmotion").setup({
  cursor = {
    duration = 100,
    easing = "linear",
  },
  scroll = {
    duration = 500,
    easing = "ease-out",
  },
})

Performance-Oriented Setup

require("luxmotion").setup({
  cursor = {
    duration = 150,
    easing = "linear",
  },
  performance = { enabled = true },
})

🐛 Troubleshooting

• Performance Issues
  • Enable performance mode: :LuxMotionPerformanceEnable
  • Reduce animation duration: cursor = { duration = 100 }
  • Use linear easing for fastest performance
• Conflicts
  • Disable default keymaps: keymaps = { cursor = false }
  • Set your own mappings manually
• Animations Not Smooth
  • Ensure terminal supports true colors
  • Use Neovim ≥ 0.7
  • Lower scrolloff for large jumps
